translucent lamp and Japanese rice paper panel

spexel

I'm trying to build an environment in UE4 of a Japanese styled room but I'm having a hard time figuring out how to recreate those effects:

I guess the same effect is needed for the panels. Anyone know a good tutorial on how to achieve this? Either inside of Substance designer or UE4.

Thanks!

The easiest solution would be to make it opaque and use an emissive material on it to give it the appearance that light is shining through it.

The main issue with ricepaper is that it is not really "translucent", the light shining through the other side is a subsurface scattering effect. So if emissive materials do not suit your needs the next thing I would try is to use subsurface scattering. I've never used it for broad surfaces though, I'm not sure how well it would work.

When I was doing my research online I also found other people saying subsurface scattering effect would be the way to go. I guess I will have to learn what the hell this is. Any link on how to use it?

Thanks!

Its actually pretty easy to do. I've used it recently for a little environment I'm working on.

Thanks I will look into it
